As answered by people managing Keepa and Sweep.
Sweep's answer:
-Sweep keeps its own price history, so it can tell you when a "40% off" badge is sitting on the price something has been all month -It searches five stores at once — Amazon, Walmart, Best Buy, eBay and Etsy — rather than one -No AI anywhere in the price path. Every number is read from the store's listing, never predicted. When a store doesn't publish something, the app leaves a gap and names the store instead of filling it -It's funded by subscriptions, not affiliate commission, so it has no reason to talk you into buying
Sweep's answer:
-CamelCamelCamel and Keepa track price history, but only on Amazon and only on the web. Honey, Rakuten and Karma cover more stores but never tell you whether a discount is real — they earn commission when you buy, so "this sale is fake" is a sentence that costs them money.
-Sweep is the overlap: price history across five stores, with an actual verdict rather than a chart to interpret. It gets paid by subscription, so it can afford to tell you not to buy.
Sweep's answer:
People who shop online and don't trust sale prices. Deal hunters, budget shoppers, and anyone who has bought something in a sale and later found out it had been that price all along. US-based, Android, skewing younger.
Sweep's answer:
-I'm Jude, I'm 16, and I got annoyed at a "40% off" badge. The shop sets the original price and the shop sets the discount, so you're taking their word for both and there's usually no way to check. -So I built something that keeps its own record of what things cost. Everything else in the app grew around that one idea. I wrote all of it — the app, the servers, the scrapers, at weekends and in the evenings.
Sweep's answer:
-React Native and Expo (TypeScript) -Fastify on Node.js -PostgreSQL with Prisma -Supabase for auth, Railway for hosting -RevenueCat for subscriptions, Sentry for error tracking

No shit. Honestly if you aren't using one of those price tracking extensions on Amazon you're doing it wrong. I use Keepa. It's amazing how many product prices are now a square wave. Look at this for example and feel sorry for the people... - Source: Hacker News / about 1 year ago
